-I-Iaving thus-described my invention, what I claim is:

'1. In comb nation with a liquid containmg tank having an exit opening, a valve within the" tank for closing such opening, a

' spring which acts to force said'valve to Its seat, said valve having a reciprocable stem, a rotatable shaft having one end outside of shaft and having a slot at the outer end when turned to either the valve c osing posithereof adapted to receive the end of said valve stem and'means for lockin said shaft at the valve and its auto-.

memes tion or valve releasing position, substantially as described.

2.- In combination with a liquid containing tank having an exit opening, a valve for closing such opening, a reciprocable valve stem connected to said valve, a spring acting to press said valve to its seat, a rotatable shaft having a slotted arm for engaging the end of said stem, said valve spring and slotted arm being within the tank, said shaft being mounted in shaft being provided with a pair of periph eral locking slots, a knob on the outer end of said shaft and a key-controlled lock mounted on the outside of the tank and having a bolt adapted to either one of said slots, scribed.

In witness whereof, I have hereunto set my hand and seal at Indianapolis, Indiana, this first day of October, A. D. nineteen hundred and thirteen.
